}

Here Is my server code....

@RequestMapping(value = "/savemobileUser", method = RequestMethod.POST)
public @ResponseBody String saveUser(@RequestBody MobileUserModel mobileUser) {

    MobileUserModel user = new MobileUserModel();
    user.setActivationKey(mobileUser.getActivationKey());
    user.setCity(mobileUser.getCity());
    user.setEmail(mobileUser.getEmail());

    user.setImeino(mobileUser.getImeino());

    user.setName(mobileUser.getName());

    user.setPassword(mobileUser.getPassword());

    user.setPhoneno(mobileUser.getPhoneno());

    userrepository.save(user);

    System.out.println("Saved");

    // return "User has been saved Successfully";
    return "SUCCESS";

}

Answer 1

Put following inside your onClick method:

switch (v.getId()) {
        case R.id.bRegister:


            // add your registration process code here



            break;
}

Please provide your json response format and also the parameter type that you are sending. It may occur due to different reasons, for example, there is an json array in response and you are mapping it just in simple object or the attributes (variable) that you are mapping into it, names are not exactly similar to json response filed or there can be different multiple reasons.
